...Hallyu began roughly 12 years ago when the rest of Asia discovered Korean soap operas. One of the breakthrough dramas was a series 'Winter Sonata' starring Choi Ji-woo & Bae Young-Joon. After that, more Korean dramas saw their way to foreign shores and Korean films and music started to follow suit. Korean marketing people started to see a Korea-centric trend. They dubbed this flow "The Korean Wave" or Hallyu....

Ha-na was anxious after being seen together with Han Tae-seong (Kim Yeong-kwang) who liked her, by Joon. Previously, Ha-na had an argument with Seo Joon's mother Baek Hye-jeong (Yoo Hye-ri), about Seo Joon so she couldn't help but be more concerned.

However, Seo Joon waited for her at her home and comforted her, "I'm sorry, were you hurt because of me?" and kissed her on the forehead as he continued, "Promise not to run even in hard times".

However still, Baek Hye-jeong continued to bully them. She met with Ha-na once again and spilled out that her mother was sick. She said, "She might become blind in a year. Let Joon go since it's not going to work". Ha-na spilled tears of shock.

However, Seo Joon knew about Kim Yoon-hee (Lee Mi-sook's) illness and that she would become blind but he didn't say a word on her favor. However, he requested treatment from Lee Seon-ho's (Kim Si-hoo) father and doctor Lee Dong-wook (Kwon In-ha). Joon made up his mind and told Seo In-ha (Jeong Jin-yeong) about Yoon-hee.

Unfortunately, Seo In-ja, Seo Joon, Kim Yoon-hee and Jeong Ha-na met again in the hospital. Yoon-hee's blind truth was revealed and it seems like the four of them are clear out soon.
